Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines extrusionskaschierten bzw. eines heißlaminierten extrudierten Folienschlauches. Darüber hinaus betrifft die vorliegende Erfindung die Verwendung eines derartig hergestellten Folienschlauches für medizinische Anwendungen.The present invention relates to a process for producing an extrusion-laminated or a hot-laminated extruded film tube. Moreover, the present invention relates to the use of a film tube produced in this way for medical applications.
Mehrlagige, kaschierte Kunststofffolien sind bekannt. Aus diesen bekannten Folien lassen sich durch Heißsiegeln Schläuche herstellen. Die Herstellung von entsprechenden Schlauchfolien ist beispielsweise in der
Darüber hinaus ermöglicht die Verfahrensweise gemäß
Da die in dem Folienschlauch innenliegenden Seiten zunächst "offene Seiten" der Kunststofffolien sind, werden innenseitig partikelarme bzw. partikelfreie Folienschläuche nur dann erhalten, wenn entweder alle Verfahrensschritte zur Herstellung der Folienschläuche in Reinräumen durchgeführt werden oder aber nach Herstellung des Folienschlauches dieser innenseitig mit sterilgefilterter Luft geflutet wird. Jedoch selbst unter Reinraumbedingungen lässt sich nicht ausschließen, dass aufgrund der elektrostatischen Aufladung der Folienschläuche Verunreinigungen in den Innenraum der Folienschläuche gelangen können.Since the inner sides of the film tube are initially "open sides" of the plastic films, particle-poor or particle-free film tubes are obtained on the inside only if all process steps for producing the film tubes are carried out in clean rooms or after production of the film tube on the inside with sterile-filtered air is flooded. However, even under clean room conditions can not be ruled out that due to the electrostatic charging of the film tubes impurities can get into the interior of the film tubes.
Aufgabe der vorliegenden Erfindung ist es demgemäß, ein Verfahren zur Herstellung eines Folienschlauches bereitzustellen, durch welches auf wirtschaftlich einfache Weise ein Folienschlauch mit einer Funktionsschicht bereitgestellt wird, wobei die Innenseite des Folienschlauches vorzugsweise im Wesentlichen partikelfrei ist und die Funktionsschicht eine niedrige Wasserdampf- und Gasdurchlässigkeit aufweist.The object of the present invention is accordingly to provide a method for producing a film tube by which a film tube is provided with a functional layer in an economically simple manner, wherein the inside of the film tube is preferably substantially free of particles and the functional layer has a low water vapor and gas permeability ,
Gelöst wird diese Aufgabe durch ein Verfahren zur Beschichtung eines extrudierten Folienschlauches.This object is achieved by a method for coating an extruded film tube.
Gegenstand der Erfindung ist somit ein Verfahren zur Herstellung eines kaschierten Folienschlauches, umfassend das im Anspruch 1 definierte Verfahren.The invention thus provides a method for producing a laminated film tube, comprising the method defined in claim 1.
Das erfindungsgemäße Verfahren gemäß einer erster Ausführungsform umfasst dann die folgenden Verfahrensschritte zur Herstellung eines extrusionskaschierten Folienschlauches:
- (a') Herstellen eines Folienschlauches durch Schmelzextrusion des Kunststoffes, wobei der Innenraum des Folienschlauches vorzugsweise mit steril gefilterter Luft geflutet wird;
- (b') gegebenenfalls Abkühlen des in Verfahrensschritt (a') hergestellten Folienschlauches;
- (c') Beschichten des gegebenenfalls abgekühlten Folienschlauches mit einer Haftkleberadhäsivschicht auf mindestens einer Seite des Folienschlauches;
- (d') gegebenenfalls Trocknen des mit der Haftkleberadhäsivschicht versehenen Folienschlauches;
- (e') Kaschieren der mindestens einen mit der Haftkleberadhäsivschicht beschichteten Seite des Folienschlauches mit einer Funktionsschicht;
- (f) gegebenenfalls Trocknen bzw. Aushärten des kaschierten Folienschlauches.
- (a ') producing a film tube by melt extrusion of the plastic, wherein the interior of the film tube is preferably flooded with sterile filtered air;
- (b ') optionally cooling the film tube produced in process step (a');
- (c ') coating the optionally cooled film tube with a pressure-sensitive adhesive layer on at least one side of the film tube;
- (d ') optionally drying the film tube provided with the pressure-sensitive adhesive adhesive layer;
- (e ') laminating the at least one side of the film tube coated with the pressure-sensitive adhesive adhesive layer with a functional layer;
- (f) optionally drying or curing of the laminated film tube.
Erfindungsgemäß ist somit vorgesehen, dass zunächst ein Folienschlauch durch Schmelzextrusion hergestellt wird, wobei der hierbei erhaltene Folienschlauch dann vorzugsweise unmittelbar auf mindestens einer Seite des Folienschlauches mit einer Haftkleberadhäsivschicht versehen wird. Auf diese Haftkleberadhäsivschicht wird dann die erforderliche Funktionsschicht aufgetragen.According to the invention, it is thus provided that initially a film tube is produced by melt extrusion, wherein the film tube obtained in this case is then preferably provided with a pressure-sensitive adhesive adhesive layer directly on at least one side of the film tube. The required functional layer is then applied to this pressure-sensitive adhesive adhesive layer.
Insbesondere Folienschläuche, die für medizinische Zwecke hergestellt werden, sollten in dem resultierenden Innenraum des Folienschlauches zumindest partikelfrei sein. Wenn ein beschichteter Folienschlauch aus einlagigen einzelnen beschichteten Folien erzeugt wird, hat dieses, wie bereits dargelegt, den Nachteil, dass der Innenraum des resultierenden Folienschlauches nicht im Wesentlichen partikelarm ist. Im erfindungsgemäßen Verfahren wird daher vorgeschlagen, dass zunächst ein Folienschlauch erzeugt wird, wobei dabei der Innenraum des Folienschlauches vorzugsweise mit steril gefilterter Luft geflutet wird. Die beiden parallelen innenliegenden Seiten des Folienschlauches haften nach der Schmelzextrusion des Folienschlauches vorzugsweise unmittelbar aufeinander, so dass eine Beschichtung der Außenseiten des Folienschlauches bei einem geschlossenen Innenraum des Folienschlauches möglich ist. Der dabei geschlossene Innenraum, der bei einer späteren Verwendung des resultierenden Folienschlauches aufgebläht wird, ist damit im Wesentlichen partikelfrei.In particular, film tubes that are produced for medical purposes should be at least free of particles in the resulting interior of the film tube. If a coated film tube is produced from single-layered single-coated films, this has, as already stated, the disadvantage that the interior of the resulting film tube is not substantially particle-poor. In the method according to the invention, it is therefore proposed that initially a film tube is produced, wherein the interior of the film tube is preferably flooded with sterile filtered air. The two parallel inner sides of the film tube preferably adhere to each other after the melt extrusion of the film tube, so that a coating of the outer sides of the film tube in a closed interior of the film tube is possible. The thereby closed interior, which is inflated at a later use of the resulting film tube is thus substantially free of particles.
In dem erfindungsgemäßen Verfahren ist es auch möglich, dass der in Verfahrenschritt (a') hergestellte Folienschlauch beidseitig kaschiert wird. Zu diesem Zweck kann beispielsweise eine Seite des Folienschlauches mit dem Haftkleber beschichtet werden und der mit dem Haftkleber beschichtete Folienschlauch dann gegebenenfalls gekühlt werden. Die mit dem Haftkleber beschichtete Seite des Folienschlauches wird dann mit einer Funktionsschicht kaschiert. Im Anschluss kann der so einseitig kaschierte Folienschlauch gegebenenfalls gekühlt werden. Anschließend wird die zweite Seite des Folienschlauches mit dem Haftkleber beschichtet. Der mit dem Haftkleber auf der zweiten Seite beschichtete Folienschlauch kann gegebenenfalls gekühlt und dann mit einer weiteren Funktionsschicht kaschiert werden. Anschließend kann der beidseitig kaschierte Folienschlauch gegebenenfalls noch einem Kühlungsschritt oder einer Wärmebehandlung unterzogen werden.In the method according to the invention, it is also possible that the film tube produced in process step (a ') is laminated on both sides. For this purpose can For example, one side of the film tube are coated with the pressure-sensitive adhesive and the coated with the pressure-sensitive adhesive film tube then optionally cooled. The coated with the pressure-sensitive adhesive side of the film tube is then laminated with a functional layer. Subsequently, the so-one-sided laminated film tube can optionally be cooled. Subsequently, the second side of the film tube is coated with the pressure-sensitive adhesive. The film tube coated with the pressure-sensitive adhesive on the second side can optionally be cooled and then laminated with a further functional layer. Subsequently, the laminated on both sides film tube may optionally be subjected to a cooling step or a heat treatment.
Darüber hinaus ist es auch möglich, dass der in Verfahrensschritt (a') hergestellte Folienschlauch beidseitig kaschiert wird, wobei die Beschichtung des Folienschlauches mit dem Haftkleber und/oder der Funktionsschicht auf beiden Seiten des Folienschlauches zumindest teilweise gleichzeitig erfolgt.Moreover, it is also possible for the film tube produced in method step (a ') to be laminated on both sides, wherein the coating of the film tube with the pressure-sensitive adhesive and / or the functional layer takes place at least partially simultaneously on both sides of the film tube.
In dem erfindungsgemäßen Verfahren gemäß erster Ausführungsform wird vorzugsweise ein Haftkleber verwendet, der eine vollständige Abbindung nach ungefähr 2 Wochen ermöglicht. In einer Wärmekammer kann die Abbindung bei erhöhter Temperatur, vorzugsweise 30°C oder mehr, beispielsweise bei 40 °C, auch schneller erfolgen.In the method according to the first embodiment of the invention, it is preferable to use a pressure-sensitive adhesive which allows complete setting after about 2 weeks. In a heat chamber, the setting at elevated temperature, preferably 30 ° C or more, for example, at 40 ° C, also faster.
Geeignete Adhäsivmaterialien sind beispielsweise Isocyanate, Polyurethane, Poly(ethylacrylat/methacrylsäureester), Reinacrylatcopolymerisate, Vinylester-/Acrylat-Copolymerisate oder anorganische-organische Hydridpolymere, wie sie beispielsweise in der
In einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung wird der Adhäsivkleber so gewählt, dass er die Anforderungen von Pharmakopoe Limits, beispielsweise hinsichtlich von Migrationseigenschaften einhält.In a particularly preferred embodiment of the present invention, the adhesive adhesive is selected to meet the requirements of pharmacopoeia limits, for example, in terms of migration properties.
Die Adhäsivschicht kann - je nach Verfahrensweise oder gewünschter Beschichtung - einseitig oder beidseitig auf den durch Coextrusion hergestellten Folienschlauch aufgetragen werden. Dieses kann beispielsweise durch Aufspritzen oder Aufrakeln erfolgen. Geeignet ist auch die Verwendung von organischen oder wässrigen Lösungen der entsprechenden Adhäsivmittel.Depending on the procedure or desired coating, the adhesive layer can be applied on one side or on both sides to the film tube produced by coextrusion. This can be done for example by spraying or knife coating. Also suitable is the use of organic or aqueous solutions of the corresponding adhesives.
Nach dem Auftragen dieser Adhäsivschichten kann der resultierende Folienschlauch gegebenenfalls getrocknet werden. Beispielsweise kann, wenn die Auftragung des Adhäsivs unter Verwendung eines organischen Lösemittels oder Wasser erfolgt, das Trocknen unter Verdunstung des Lösemittels oder des Wassers erfolgen. Die Schichtdicken der Haftkleberadhäsivschichten liegen vorzugsweise im Bereich von 3 bis 20 µm.After applying these adhesive layers, the resulting film tube can optionally be dried. For example, when the adhesive is applied using an organic solvent or water, drying may be carried out with evaporation of the solvent or water. The layer thicknesses of the pressure-sensitive adhesive adhesive layers are preferably in the range of 3 to 20 μm.
Es ist besonders bevorzugt, wenn die so erzeugte Adhäsivschicht bereits eine Wasser- und/oder Gasbarriere auf dem extrudierten Folienschlauch bildet.It is particularly preferred if the adhesive layer thus produced already forms a water and / or gas barrier on the extruded film tube.
In einer weiteren Ausführungsform ist es auch möglich, die Adhäsivschicht nicht auf den extrudierten Folienschlauch aufzutragen, sondern auf die auf den Folienschlauch aufgebrachte Funktionsschicht, welche weiter unten beschrieben wird.In a further embodiment, it is also possible not to apply the adhesive layer to the extruded film tube, but to the functional layer applied to the film tube, which will be described below.
Die Kaschierung in der ersten Ausführungsform des erfindungsgemäßen Verfahrens kann vorzugsweise mittels Kaschierwalzen oder auf Kalandern bei Raumtemperatur erfolgen.The lamination in the first embodiment of the process according to the invention can preferably take place by means of laminating rolls or on calanders at room temperature.
In einer zweiten Ausführungsform wird die Aufgabe der vorliegenden Erfindung durch ein Verfahren gemäß Anspruch 1 zur Herstellung eines heißlaminierten extrudierten Folienschlauches gemäß Anspruch 5 gelöst.In a second embodiment, the object of the present invention by a method according to claim 1 for the preparation of a hot-laminated extruded film tube according to claim 5 is achieved.
Das erfindungsgemäße Verfahren gemäß dieser zweiten Ausführungsform ist durch folgeende Verfahrensschritte gekennzeichnet:
- (a") Herstellen eines Folienschlauches durch Schmelzextrusion eines Kunststoffes;
- (b") gegebenenfalls Abkühlen des in Verfahrensschritt (a") hergestellten Folienschlauches;
- (c") Heißlaminieren des gegebenenfalls getrockneten Folienschlauches mit einer Funktionsschicht.
- (a ") producing a film tube by melt extrusion of a plastic;
- (b ") optionally cooling the film tube produced in process step (a");
- (c ") hot lamination of the optionally dried film tube with a functional layer.
Da in Verfahrensschritt (c") ein Heißlaminieren des Folienschlauches vorgesehen ist, ist es bevorzugt, wenn die Funktionsschicht temperaturunempfindlich ist.Since hot lamination of the film tube is provided in method step (c "), it is preferred if the functional layer is insensitive to temperature.
Auch gemäß der zweiten Ausführungsform des erfindungsgemäßen Verfahrens ist es möglich, dass der in Verfahrensschritt (a") hergestellte Folienschlauch beidseitig kaschiert wird. Zu diesem Zweck kann die Heißlaminierung mit der Funktionsschicht nach dem Herstellen des Folienschlauches durch Schmelzextrusion eines Kunststoffes und gegebenenfalls Abkühlen des so hergestellten Folienschlauches zunächst auf der einen Seite und dann auf der anderen Seite des Folienschlauches erfolgen. Genauso ist es möglich, dass der Folienschlauch auf beiden Seiten zumindest teilweise gleichzeitig mit der Funktionsschicht heißlaminiert wird. Vor dem Kaschieren einer jeden Seite ist es jedoch bevorzugt, dass der Folienschlauch nach dem Abkühlen flachgelegt wird.In accordance with the second embodiment of the method according to the invention, it is also possible for the film tube produced in process step (a ") to be laminated on both sides, for which purpose the hot lamination with the functional layer can take place after the Producing the film tube by melt extrusion of a plastic and optionally cooling the film tube thus produced first on one side and then done on the other side of the film tube. It is equally possible for the film tube to be hot-laminated at least partially simultaneously with the functional layer on both sides. Before laminating each side, however, it is preferred that the film tube be laid flat after cooling.
Gemäß beiden Ausführungsformen des erfindungsgemäßen Verfahrens ist es bevorzugt, dass der Folieninnenraum während des oder der Kaschiervorgänge bzw. des oder der Heißlaminierungen geschlossen verbleibt, so dass es sich hierbei um einen im Wesentlichen partikelarmen bzw. partikelfreien Folieninnenraum handelt.According to both embodiments of the method according to the invention, it is preferred for the film interior to remain closed during the lamination process or for the hot lamination (s), so that this is a substantially particle-poor or particle-free film interior.
In dem erfindungsgemäßen Verfahren gemäß erster und gemäß zweiter Ausführungsform wird der in Verfahrensschritt (a') bzw. (a") zur Herstellung des Folienschlauches verwendete Kunststoff ausgewählt aus der Gruppe, bestehend aus Polypropylen, Polyethylen-Copolymeren, Styrol-Ethylen/Butylen-Styrol-Blockcopolymeren (SEBS), Styrol-Isopren-Styrol-Blockcopolymeren (SIS) und thermoplastische Elastomere (TPE).In the process according to the invention according to the first and second embodiments, the plastic used in process step (a ') or (a ") for producing the film tube is selected from the group consisting of polypropylene, polyethylene copolymers, styrene-ethylene / butylene-styrene Block copolymers (SEBS), styrene-isoprene-styrene block copolymers (SIS) and thermoplastic elastomers (TPE).
Die in beiden Ausführungsformen des vorliegenden Verfahrens gegebenenfalls durchzuführenden Verfahrensschritte des Abkühlens können jeweils außenseitig auf dem vorzugsweise geschlossenen Folienschlauch beispielsweise durch Luft erfolgen. Auch ist es möglich, den Trocknungsvorgang in einem Trockenkanal durchzuführen.The process steps of cooling, which may optionally be carried out in both embodiments of the present method, may be carried out on the outside of the preferably closed film tube, for example by air. It is also possible to carry out the drying process in a drying tunnel.
Die Herstellung des erfindungsgemäß vorgesehenen Folienschlauches durch Schmelzextrusion eines Kunststoffes kann in jeder, dem Fachmann an sich bekannten und geeigneten Extrudervorrichtung erfolgen. Als Beispiel sei ein Einschneckenblasextruder genannt.The preparation of the film tube provided by melt extrusion of a plastic according to the invention can be carried out in any extruder device known and suitable to a person skilled in the art. An example is a single-screw extruder.
